TRIMMER.

Application filed October 19, 1925. Serial, No. 63,346.

eter,' these trimmers having no means for varying the position of their blade to vary its cutting depth. It is necessary, however, at times to trim. the terminals to different diameters so; that. connectors of different sizes; may be fitted thereon.

Trimmers now in use are also awkward to handle because they have to be rotated a continuousrevolution to; trim a terminal; which necessitates. releasing the hand and taking another-grip on the; trimmer after each revolution. p

An important object of my invention is toprovide a trimmer for trimming} storage battery terminals to any desired diameter so that. connectors of any size may be fitted thereon.

Another object is to provide 'a trimmer which will effectively trim storage battery terminals when rotated only 90 degrees alternately in opposite directions without releasing thehand from thedevice. i V Another object is to. provide a trimmer of-the character stated which may be attached to' and made apart of a pairof pliers. Other objects will appear as the description progresses. i My invention isillustrated in the annexed 1 drawing forming a part of this specification,

Fig. 1 is a side elevation of my trimmer shown applied to a storage battery terminal and, grasped by ones hand in the act of trimming said terminal.

Fig. 2 is a side elevation ofone form of my trimmer as embodied in a pair of pliers. Fig. 3 is a side elevation of another form of my trimmer with the pliers eliminated. Figs. 4 and 5 are horizontal sections ofmy trimmer taken on line 4 4: of Fig. 1, showing the trimmer in the act of being turned alternately in opposite directions and trimming a storage battery terminal- Fig. 6 is an inside view of one ofthe trimnierblade members.

My invention includes a pair of pivoted handles 1 and 2 pivoted at one end at 3, and a pair of yieldable trimmer members 41 and 5 mounted on the inside of said handlesfrespectively with the outer ends of said memsaid handles. v 5 is formed of a single piece of sheet. metal ,and'comprises a double-edged conical blade 6; a flat spring 7, a blade shank 8, anda pair blade andspring, theshank 8 extending in} here coinciding with the swingingends of Each trimmer member 4t and of spaced fork arms 9011 its innerwend, the

wardly from the inner end of the: blade and the arms; 9 being bent; from the side edges 1 of the shank at the inner end thereof; and

at right angles thereto. The springs 7 of the, trimmer members 4 and 5 are secured at their inner ends by rivets 11to the inner edges of the handles-1 and 2; respectively, with the outer ends ofthe trimmer members or junctur'es; 10 coinciding with the outer ends ofthe handles and with the arms 9 of the trimmer members straddlingthe handles respectively, from the inner edges thereof'so thatsaid arms engagethe opposite sidesof said handles. The opposite side edgeso-f the blades '6 are sharpened to'the inner surface oftlie blades to form blade edges 12 and 13, which edges converge from theouter to the inner ends of the blades owing to The cross sectional curvature of the blades is of less radius than the radius of theconical lead terminal T of the storage battery B, so that the inner surface of'the blades will be spaced from the surface of the terminal and only the blade edges 12 and18 of the trimmer blades 6 will contact with the surface of p the terminal in true trimming relation to the terminal. The blades 6. are wider than 1 the springs 7 and the lowerends 14 and 15 of the blades outsidethe side edgesof the springs are bent outwardly and upwardly I so that said ends will not the user of the device. I

The springs 7 except at their points of attachment at their inner ends to the handles 1 and 23 rest inwardly from the handles -in spaced relation thereto so that the blades 6 may yield outwardly to lit the terminal '1 or when the handlesare compressed inwardly with toogreat a force;

V The handle 2 is provided with a threaded out the hand of a tends through a slot 18 in the member 1, the screw having a knurled head 19 for engaging the handle 1 to hold the handles 1 and 2 and the trimmer blades 6 apart at a predetermined distance for trimming the terminal to a predetermined diameter.

My trimmer may be embodied in a pair of pliers P as shown in Fig. 2, the plier handles and their pivot corresponding to the handles 1 and 2 and pivot 3 above describe-Ll, and the plier jaws 20 and 21 being formed on the pivoted ends of said handles. The blades 6 may be limited to their smallest cutting diameter by the engagement of the jaws 20 and 21 in closed posigrees of the surface of the terminal and when the device is reversed and turned 90 degrees clockwise the remaining 180 de rees of the terminal is t immed by theedges 13, thuscompletely trimming the terminal in two one quarter turns of the device alternately in opposite directions.

The diameter to which the terminal is trimmed depends upon the pressure applied to the handles 1 and 2 or the dis ance to which the handles are held apart, whi h dis tance may be fixed by tightening the screw While I have shown and described a preferred embodiment of my invention, it will beunderstood that I may change or modify the same within the scope of the appended claims'without departing from the spirit thereof.

hat- I claim is:

1. A trimmer of the character described comprising a pair of plier members pivoted together intermediate the handles and jaws and forming supporting members and a pair of sheet metal blades mounted on the inner sides of said handles in opposition to each other, said blades having cent al arcuat'e portions-with cutting edges thereon, and being spaced apart for engaging opposite portions of the work to be trimmed.

' 2. The trimming tool comprising a pair of pliers, members pivoted together at a point intermediate the handles and jaws and forming supporting members and a pairof sheet metal trimmers resiliently mounted on the inner sides of said handles and in opposition to each other, said trimmers having extensions attached to said handles, trimming blades of arcuate cross section arranged for engagement with opposite portions of the work to be trimmed, and eaten sions from said blades engaging the sides of said handles for holding the blades in op erative position.

3. A trimming tool comprising a pair of pivoted supporting members and a pair of trimmers mounted thereon in opposition to each other, said trimmers having extensions attached to said supporting members for resiliently supporting the same, and arouate blades capable of being spread apart and resiliently held in contact with opposite portions of the work to be'trimmed, said. blades being formed on a radius less than the ra dius of the Work.
